Keep getting message Satelite signal not available

[cuan22]

For the last while when we turn the TV on we often get the messgage Satelite signal not available. At first we assumed that it was a problem with the dish or the wires from the dish to the Sky+HD box. But then I discovered that some channels work OK - STV and Channel 5 to mention  a couple. The BBC channels were showing the error message. Earlier today, I turned the Sky box off at the wall and left it off for a good few minutes. When I restarted the box, everything seemed to work again althought here was some interference to the picture on BBC1. What I would like to know is if the problem is with the dish and wiring or is it a sign that our sky box is dying a slow death? (That will be a nightmare as I do not wish to upgrade as our TVs are so old they would not be able to connect to the Sky Q box) Any advice appreciated.

It's unlikely (but not impossible) to be a problem with your Sky box. Much more likely to be a dish or cabling problem - in particular the LNB where the cables connect at the dish end may be failing as they often do after 5 years or so.

It's perfectly possible to have a good signal on some channels, and no signal on others.

So you think that it is more likely to be a problem with the dish? I assume that it would be necessary to call out a  sattelite engineer to sort that as it would not be something that my hysband could buy bits for and do himesel?

Yes, more likely a dish issue, I think. It would be best to get a local satellite engineer to take a look. If the dish is slightly out of alignment you would need a good (i..e. expensive!) signal meter to be able to re-align it accurately. It only has to be a degree or so out to disrupt the signal to some channels.
